A US panel investigating the crimes of Jeffrey Epstein has requested that the executors of his estate produce a number of documents, including a book said to have contained personal messages for his 50th birthday. The subpoena from James Comer, the leader of the House Oversight Committee, represents an expansion of his investigation into Epstein, the disgraced late paedophile financier.

Last month, the Wall Street Journal reported that the birthday book his associate Ghislaine Maxwell created in 2003 contained submissions from various Epstein acquaintances, including a bawdy note allegedly bearing the name of Donald Trump, who was then his friend. Trump has denied writing any such letter.

Comer's subpoena asks that the executors of Epstein's estate provide 'all entries contained within the reported leather-bound book compiled by Ms Ghislaine Maxwell'. It gives a deadline of 8 September for the item to be turned over.

A lawyer for the Epstein estate confirmed receipt of the request, and said the executors would 'comply with all lawful process in this matter, and that includes the Committee's subpoena'. Among other papers, it also requests any non-disclosure agreements executed by Epstein over a three-decade period, and his will preceding his death in jail in 2019. It further demands 'any document or record that could be reasonably construed to be a potential list of clients involved in sex, sex acts, or sex trafficking' by Epstein.

Conspiracy theories persist, and pressure grows from Trump's supporters for more transparency on the so-called 'Epstein files'. This investigation is unfolding as Comer previously issued subpoenas to various individuals, including the former President and Secretary of State. The political ramifications continue to be significant, with Trump stating he would have been open to revealing more information regarding his connections to Epstein, but has since shifted his stance, expressing that the case is closed.
